I really like it. I have the Start Screen set up the way I like it, it's fast, all my programs work and I really like the RTM theme. Still haven't come across any "Modern" apps I'd actually want to use on my non-tablet computer. But it's early days.

Something went wrong with the install the first time (upgrade install), and it got stuck in a loop of going into recovery mode, and it saying it was unable to fix the problem. Restored a backup and tried again and it worked (which is why I gave the install 2/5).

So far, 5/5 on the first 2, compatibility is excellent and the install process is quick and easy, but I only gave 3/5 on the last one as I simply cannot stand the start screen and I think the themes are absolutely horrible

The setup was easy enough with only a couple of hiccups which had more to do with the laptop than the OS.

Compatibility is also a 4/5 because anything I tried to install seemed to work without problems. It doesn't get 5/5 because it was impossible for me to test everything for compatibility with the short time that I was using it.

2/5 for the features. It's not because I found features to be missing compared to previous versions of Windows, but rather because while all the features that I would normally use may have been there, I found them very difficult to find.

Providing I can fix up this laptop soon, I may give the Windows 8 trial a go and see how it has improved. I'm pretty sure the above scoring won't change for me though.

It feels more complete but some things I'm unsure how they were passed by testing. Things like padding in text boxes in the apps and the title colour staying a near black when using a black window colour. It's a good upgrade from WIndows 7 but it still feels unfinished in areas.

For the most part pretty happy with it. Speed and compatibility is excellent, so far everything works and pretty quickly at that. Experience wise it needs a bit of polish in a few areas yet, but for a first release that's to be expected. Start screen I'm quickly falling in love with. (Mostly, again needs a few tweaks.) Think the only thing I'm probably not very happy with is the default desktop theme... but then again I pretty much hate the default theme in any OS regardless, waiting for the third party modders to get busy releasing.

Installation: 5/5 (Installed in <10mins on a non SSD system)
Compatibility: 5/5 no problems whatsoever
Features: 4/5
some of the necessary apps such as Music, Video, Photos, Messaging and Mail still feel unfinished. (for example, the Mail doesn't pick up my custom highlight color)
I like the new start screen customization option, that really makes it look better but they should still provide an easy option for custom backgrounds.
Desktop themes is a hit-miss, I don't really play around with this stuff anymore but the default unfocused windows are difficult to tell apart when they overlap.
